Megyn Kelly makes shocking sexual-harassment allegations against Roger Ailes in leaked passages of new book

Megyn Kelly. AP Photo/Chris Carlson Fox News host Megyn Kelly alleges in her new book that Roger Ailes, the network's longtime former CEO, made unwanted sexual advances on her years ago, according to excerpts obtained by Radar Online and published Thursday.

"I was approached several times, and several times I refused," Kelly wrote in the book, "Settle For More," according to the excerpts published by Radar Online.

The rising Fox News star wrote that Ailes "began pushing the limits" when she joined the network as a legal correspondent, according to Radar Online.

"I would be called into Roger's office, he would shut the door, and over the next hour or two, he would engage in a kind of cat-and-mouse game with me — veering between obviously inappropriate sexually charged comments (e.g. about the 'very sexy bras' I must have and how he'd like to see me in them) and legitimate professional advice," she reportedly wrote.

Kelly wrote that Ailes said offered to advance her career "in exchange for sexual favors," according to Radar Online. She said she rebuffed "every single one" of his sexual advances, but that in early 2006 he became more aggressive, according to Radar Online.

Ailes "crossed a new line — trying to grab me repeatedly and kiss me on the lips," Kelly reportedly wrote.

According to Radar Online, Kelly wrote that when she rejected Ailes, he asked "When is your contract up?"

Through his lawyer, Susan Estrich, Ailes denied the allegations against him and pointed to positive comments Kelly made about him last year.

A spokesperson for Kelly would not confirm the authenticity of the excerpts published by Radar Online.

Ailes resigned from Fox News in July after former host Gretchen Carlson filed a lawsuit against the network alleging Ailes sexually harassed her for years. The lawsuit was settled for a reported $20 million.

Carlson's allegations against Ailes led 21st Century Fox to order an investigation. According to reports, Kelly cooperated and detailed her experiences with Ailes to the law firm conducting the review.

Kelly's book is due out on November 15.
